Delete a context in Greenhopper 3.8?

Sorry for the question on an ancient version of Greenhopper, but I have what I have. Anyone know how to delete a context in Greenhopper 3.8? I finally figured out how to edit an existing context, but I can't seem to be able to get rid of a context once I've created it.

...It's true that there are projects in Jira; but they are merely a way to cut off issues, to tell them apart from other sections of work and to apply rules that are specific to that team (the schemes)....
